Hello, my name is ***** ***** I'm here to help get your problem solved.
It sounds like your catalytic converter is clogged which will make it run like you are describing and set oxygen sensor code. Completely remove front oxygen sensors from exhaust to see if it runs better, if so you know converter is clogged and needs to be replaced. Let me now how it goes or if you have more questions, thanks.
It definitely sounds like a converter problem, when check engine light flashes it means there is a cylinder misfire. Let me know how it goes or if you run into more questions, thanks.
